This is the summary of the bug I am having.

What I expected to happen was that the doors were to stay closed

What actually happened was the doors reopen when you sleep in your bed and/or are a distance way for a long time from the door. It also opens when you exit out of the app.

Steps to Reproduce:
1. Place a door or trapdoor down in survival and have them closed
2. Move a set amount away from the doors, maybe 30/40 blocks?
3. Sleep in a bed for the night then return to the doors you places
4. The doors most of the time are found opened again
